Why two NDCs? The FDA registers this code as 63629-1917-1 — a 5-4-1 layout, and that's what's printed on the package and shown on DailyMed. For insurance claims, every NDC is standardized to a uniform 11-digit 5-4-2 format by adding a zero to the package segment → 63629-1917-01. Same drug, same package — only the format differs.

Label name LITHIUM CARBONATE 300 MG CAP Ingredient Lithium Carbonate
📖 What it is MedlinePlus · NLM

Lithium is used to treat and prevent episodes of mania (frenzied, abnormally excited mood) in people with bipolar disorder (manic-depressive disorder; a disease that causes episodes of depression, episodes of mania, and other abnormal moods). Lithium is in a class of medications called antimanic agents. It works by decreasing abnormal activity in the brain.

Nutrient depletion considerations

Lithium Carbonate (prescription drug) may be associated with lower levels of 1 nutrient — worth a chat with your pharmacist, not a cause for alarm.

An association is not a deficiency. Educational only — don't start or stop anything without professional guidance.
Where does this data come from?
Plain-language summary from MedlinePlus (U.S. National Library of Medicine); supplement & herbal interactions and nutrient depletion data from the Natural Medicines database; our full guide is HelloPharmacist editorial content.

🧪 Inactive Ingredients / Excipients

Inactive ingredients, also called excipients, are components of the drug product other than the active ingredient. They may include fillers, dyes, coatings, preservatives, flavors, or other formulation ingredients.

We could not link this NDC to a current FDA Structured Product Label. An inactive-ingredient list is therefore not available from this source.
Where does this data come from?
Source: official FDA Structured Product Labeling (SPL) via DailyMed and the openFDA label index. Structured IACT rows and label-wide narrative are kept separate; availability and product-level specificity depend on the submitted label.

Inactive ingredient FAQ

Are inactive ingredients the same for every manufacturer?
No. Inactive ingredients can differ by manufacturer, dosage form, strength, and package / product version.
Why might an inactive ingredient be missing?
Some SPLs do not provide a complete structured inactive-ingredient list, and older or unusual labels may only include the information in narrative text.
Can inactive ingredients matter?
Yes. They can matter for allergies, intolerances, dyes, gluten / lactose concerns, preservatives, and formulation differences — but confirm with a pharmacist or the manufacturer when it’s clinically important.

💲 Pricing

A drug doesn't have one price. Each row is a different public payment system, and none is what you'd pay at the counter — that depends on your insurance. The ⓘ on each row explains what it measures.

Price systemPer eachPer package
Retail pharmacies payNADAC · weekly Not in the retail survey — common for institutional, discontinued, or low-volume packs.
Medicaid paysCMS SDUD · 12 mo No recent Medicaid claims on file for this NDC — rare and low-volume NDCs are suppressed in the public data.
Medicare drug plans payPart D · Q2 2026 $0.1216 $121.60 / 1000 capsules
Where does this data come from?
NADAC (National Average Drug Acquisition Cost) is the CMS weekly pharmacy-acquisition-cost survey — what pharmacies pay. ASP (Average Sales Price) is the CMS Medicare Part B drug-payment file, published quarterly. Medicaid pays is computed by us from CMS State Drug Utilization Data (total reimbursed ÷ units, trailing 12 months) — gross of rebates and inclusive of dispensing fees, so it reflects what Medicaid paid, not an acquisition cost. Medicare drug plans pay is the median negotiated point-of-sale unit cost across plans listing this NDC in the CMS quarterly Prescription Drug Plan pricing files, before rebates. The VA pays is the federal contract price (FSS, and the statutory Big 4 ceiling where listed) from the VA National Acquisition Center pharmaceutical price file. All are free public government data; each measures a different payer, so the figures are not directly comparable.

📊 Medicare Part D spend CMS · PART D · 2026 (Q1)

Medicare Part D (outpatient prescription) spending for Lithium Carbonate — the program that covers self-administered drugs. 6 manufacturers.
⚠️ Drug-level data: CMS publishes Part D spending by drug, not by NDC — these figures combine every manufacturer, strength and package size sold under the name Lithium Carbonate. That’s a different level of aggregation than the Medicaid card above, which is specific to this exact 11-digit NDC (pack size included), so the two aren’t directly comparable.

💵 About the dollar figures: spending is what Part D plans paid before confidential manufacturer rebates, so the program’s real net cost is lower. A blank patient count means fewer than 11 people — CMS hides counts that small to protect privacy. Source: CMS Medicare Quarterly Part D Spending by Drug (data.cms.gov), updated quarterly.

Questions about this listing

Why is there no price listed?
The pricing shown on our NDC pages comes from CMS NADAC, a voluntary survey of retail community pharmacy invoices. CMS does not publish a NADAC for every NDC — packages outside the retail survey (institutional and hospital products, bulk packages, discontinued items, and many OTC items) may never receive one. A missing price reflects the survey's scope, not this product's actual cost, and does not mean the product is free or unavailable.
What does the discontinued status mean for this NDC?
The labeler reported a marketing end date (or the listing was delisted), so this specific package is no longer actively marketed. Remaining stock may still be dispensed for a time, and the NDC stays valid for historical records and claims — but data feeds (pricing, labeling) typically stop updating for it. Other package sizes or other manufacturers' versions of the same medication may still be marketed — see the equivalents section where available.
Is the NDC printed on the package the same as the 11-digit billing NDC?
Yes, they identify this exact package in different formats. The FDA registers it as 63629-1917-1, which is what is printed on the packaging and shown on DailyMed. Insurance claims use a fixed 11-digit 5-4-2 format, so the short segment is padded with a leading zero: 63629-1917-01, written without dashes as 63629191701. The Identity section at the top of this page lists every form of this code.
What do the three segments of this NDC mean?
In 63629-1917-01, the first segment (63629) is the labeler code FDA assigned to Bryant Ranch Prepack; the middle segment (1917) identifies this specific product — its ingredient, strength, and dosage form; and the last segment (01) identifies this exact package size and type. Together they name one specific package of one specific product.
Who lists this product with the FDA?
Bryant Ranch Prepack is the labeler of record for this NDC — the company under whose FDA-assigned code the package is listed. The labeler may be the manufacturer itself or a distributor marketing the product under its own code.
Do I need a prescription for this product?
This NDC is listed with FDA as a prescription product, so it is dispensed under a prescriber's order. Your pharmacist can tell you whether any over-the-counter forms of the same medication exist.
This page identifies an FDA-listed package (the NDC) and reports public regulatory and pricing data about the listing. It is reference information, not a medical recommendation — talk to your pharmacist or prescriber about your own medication.
Where does this data come from?
Listing facts (marketing category, packager status, marketing dates) from the FDA openFDA NDC Directory; label availability from DailyMed; pricing coverage from CMS NADAC; equivalence scope from the FDA Orange Book.

2.1Pre-treatment Screening Before initiating treatment with lithium, renal function, vital signs, serum electrolytes, and thyroid function should be evaluated. Concurrent medications should be assessed, and if the patient is a woman of childbearing potential, pregnancy status and potential should be considered.

2.2Starting Dosage Consider medical conditions and drug interactions that would affect lithium dosage and administration [see Warnings and Precautions ( 5.1 ), Drug Interactions ( 7.1 )]. In the absence of medical conditions and concomitant medications that would suggest starting at a lower dose, the recommended starting dose in adults is: • Capsules: 300 mg three times daily Obtain serum lithium concentration assay after 4 days, drawn 12 hours after the last oral dose. Adjust daily dosage based on serum lithium concentration and clinical response.

Fine hand tremor, polyuria and mild thirst may occur during initial therapy for the acute manic phase, and may persist throughout treatment. Transient and mild nausea and general discomfort may also appear during the first few days of lithium administration. These adverse reactions may subside with continued treatment, concomitant administration with food, temporary reduction or cessation of dosage.

2.3Dosage for Acute Treatment of Manic Episodes in Bipolar I Disorder Titrate to serum lithium concentrations between 0.8 and 1.2 mEq/L, which may be achieved in adults with: • Capsules: 600 mg, two to three times daily Obtain serum lithium concentrations regularly until the serum concentration and clinical condition of the patient has stabilized [see Dosage and Administration ( 2.6 )] . Adjust daily dosage based on serum lithium concentration and clinical response.

2.4Dosage for Maintenance Treatment of Bipolar I Disorder Titrate to serum lithium concentrations between 0.8 and 1 mEq/L, which may be achieved in adults with: • Capsules: 300 mg to 600 mg, two to three times daily Monitor the patient's clinical state and serum lithium concentrations regularly [see Dosage and Administration ( 2.6 )] . Adjust daily dosage based on serum lithium concentration and clinical response.

2.5Dosage Recommendations in Pediatric Patients 12 to 17 Years of Age Dosage recommendations for lithium in patients 12 years and older are similar to that of adults [see Use in Specific Populations ( 8.4 )] .

2.6Serum Lithium Monitoring Blood samples for serum lithium determination should be drawn immediately prior to the next dose when lithium concentrations are relatively stable (i.e., 12 hours after the previous dose). Total reliance must not be placed on serum concentrations alone. Accurate patient evaluation requires both clinical and laboratory analysis.

In addition to regular monitoring of serum lithium concentrations for patients on maintenance treatment, serum lithium concentrations should be monitored after any change in dosage, concurrent medication (e.g., diuretics, non-ste…

⚠️ Warnings and Cautions ~3 min read

5 WARNINGS AND PRECAUTIONS • Lithium-Induced Polyuria: May develop during initiation of treatment. Increases risk of lithium toxicity. Educate patient to avoid dehydration.

Monitor for lithium toxicity and metabolic acidosis. Discontinue lithium or treat with amiloride as a therapeutic agent ( 5.2 ) • Hyponatremia: Symptoms are more severe with faster-onset hyponatremia. Dehydration from protracted sweating, diarrhea, or elevated temperatures from infection increases risk of hyponatremia and lithium toxicity.

Educate patients on maintaining a normal diet with salt and staying hydrated. Monitor for and treat hyponatremia and lithium toxicity, which may necessitate a temporary reduction or cessation of lithium and infusion of serum sodium ( 5.3 ) • Lithium-Induced Chronic Kidney Disease: Associated with structural changes in patients on chronic lithium therapy. Monitor kidney function during treatment with lithium ( 5.4 ) • Encephalopathic Syndrome: Increased risk in patients treated with lithium and an antipsychotic.

Monitor routinely for changes to cognitive function ( 5.5 ) • Hypothyroidism and Hyperthyroidism: Monitor thyroid function regularly ( 5.7 ) • Hypercalcemia and Hyperparathyroidism: Associated with long-term lithium use. Monitor serum calcium ( 5.8 )

5.1Acute Lithium Toxicity The toxic concentrations for lithium (≥1.5 mEq/L) are close to the therapeutic range (0.8 to 1.2mEq/L). Some patients abnormally sensitive to lithium may exhibit toxic signs at serum concentrations that are considered within the therapeutic range [see Boxed Warning, Dosage and Administration ( 2.6 )] . Lithium may take up to 24 hours to distribute into brain tissue, so occurrence of acute toxicity symptoms may be delayed.

Diarrhea, vomiting, drowsiness, muscular weakness and lack of coordination may be early signs of lithium toxicity, and can occur at lithium concentrations below 2.0 mEq/L. At higher concentrations, giddiness, ataxia, blurred vision, tinnitus and a large output of dilute urine may be seen. Serum lithium concentrations above 3.0 mEq/L may produce a complex clinical picture involving multiple organs and organ systems, coma, and eventually death.

Serum lithium concentrations should not be permitted to exceed 2.0 mEq/L. Neurological signs of lithium toxicity range from mild neurological adverse reactions such as fine tremor, lightheadedness, and weakness; to moderate manifestations like apathy, drowsiness, hyperreflexia, muscle twitching, and slurred speech; and severe manifestations such as clonus, confusion, seizure, coma and death. Cardiac manifestations involve electrocardiographic changes, such as prolonged QT interval, ST and T-wave changes and myocarditis.

Renal manifestations include urine concentrating defect, nephrogenic diabetes insipidus, and renal failure. Respiratory manifestations include dyspnea, aspiration pneumonia, and respiratory failure. Gastrointestinal manifestations include nausea, vomiting, and bloating.

No specific antidote for lithium poisoning is known. Early symptoms of lithium toxicity can usually be treated by reduction or cessation of lithium, before restarting treatment at a lower dose 24 to 48 hours later [See Overdosage ( 10 )] . The risk of acute toxicity is increased with a recent onset of concurrent illness or with the concomitant administration of drugs which increase lithium serum concentrations by pharmacokinetic interactions [see Drug Interactions ( 7 )] .

Additional risk factors for acute lithium toxicity include acute ingestion, age-related decline in renal function, volume depletion and/or changes in electrolyte concentrations, especially sodium and potassium. Dose requirements during the acute manic phase are higher to maintain therapeutic serum concentrations and decrease when manic symptoms subside. The risk of lithium toxicity is very high in patients with significant renal or cardiovascular disease, severe debilitation or dehydration, or sodium depletion, and for patients receivin…

🔄 Drug Interactions ~2 min read

7 DRUG INTERACTIONS • Diuretics, NSAID, renin-angiotensin system antagonists, or metronidazole may increase lithium serum concentrations. Recommend frequent monitoring of serum lithium concentration and adjust dosage when necessary ( 2.6 , 7.1 ) • Serotonergic agents: Increased risk of serotonin syndrome when Co-administered with lithium ( 5.6 , 7.1 ) • Antipsychotics: There have been reports of neurologic adverse reactions in patients treated with lithium and an antipsychotic, ranging from extrapyramidal symptoms to neuroleptic malignant syndrome ( 5.5 , 7.1 )

7.1Drugs Having Clinically Important Interactions with Lithium Table 2: Clinically Important Drug Interactions with Lithium Diuretics Clinical Impact: Diuretic-induced sodium loss may reduce lithium clearance and increase serum lithium concentrations . Intervention: More frequent monitoring of serum electrolyte and lithium concentrations. Reduce lithium dosage based on serum lithium concentration and clinical response [see Dosage and Administration ( 2.6 ), Warning and Precautions ( 5.3 )] Examples: hydrochlorothiazide, chlorothiazide, furosemide Non-Steroidal Anti-inflammatory Drugs (NSAID) Clinical Impact: NSAID decrease renal blood flow, resulting in decreased renal clearance and increased serum lithium concentrations.

Intervention: More frequent serum lithium concentration monitoring. Reduce lithium dosage based on serum lithium concentration and clinical response [see Dosage and Administration ( 2.6 )]. Examples: indomethacin, ibuprofen, naproxen Renin-Angiotensin System Antagonists Clinical Impact: Concomitant use increase steady-state serum lithium concentrations.

Intervention: More frequent monitoring of serum lithium concentration. Reduce lithium dosage based on serum lithium concentration and clinical response [see Dosage and Administration ( 2.6 )]. Examples: lisinopril, enalapril, captopril, valsartan Serotonergic Drugs Clinical Impact: Concomitant use can precipitate serotonin syndrome.

Intervention: Monitor patients for signs and symptoms of serotonin syndrome, particularly during lithium initiation. If serotonin syndrome occurs, consider discontinuation of lithium and/or concomitant serotonergic drugs [see Warnings and Precautions ( 5.6 )]. Examples: selective serotonin reuptake inhibitors (SSRI), serotonin and norepinephrine reuptake inhibitors (SNRI), monoamine oxidase inhibitors (MAOI) Nitroimidazole Antibiotics Clinical Impact: Concomitant use may cause lithium toxicity due to reduced renal clearance.

Intervention: More frequent monitoring of serum lithium concentration. Reduce lithium dosage based on serum lithium concentration and clinical response [see Dosage and Administration ( 2.6 )]. Examples: metronidazole Acetazolamide, Urea, Xanthine Preparations, Alkalinizing Agents Clinical Impact: Concomitant use can lower serum lithium concentrations by increasing urinary lithium excretion.

Intervention: More frequent serum lithium concentration monitoring. Increase lithium dosage based on serum lithium concentration and clinical response [see Dosage and Administration ( 2.6 )]. Examples: acetazolamide, theophylline, sodium bicarbonate Methyldopa, Phenytoin and Carbamazepine Clinical Impact: Concomitant use may increase risk of toxic effects of these drugs Intervention: Monitor patients closely for symptoms of toxicity of methyldopa, phenytoin, and carbamazepine.

Iodide Preparations Clinical Impact: Concomitant use may produce hypothyroidism. Intervention: Monitor patients for signs or symptoms of hypothyroidism [see Warnings and Precautions ( 5.7 )]. Examples: potassium iodide Calcium Channel Blocking Agents (CCB) Clinical Impact: Concomitant use may increase the risk of neurologic adverse reactions in the form of ataxia, tremors, nausea, vomiting, diarrhea and/or tinnitus.

Intervention: Monitor for neurologic adverse reactions. Examples: diltiazem, nifedipine, verapamil Atypical and Typical Antipsychotic Drugs Clinical Impact: Reports of neurotoxic re…

8 USE IN SPECIFIC POPULATIONS • Pregnancy: May cause fetal and/or neonatal harm ( 8.1 ) • Renal impairment: Use caution during dose selection, starting at the low end of the dosing range while carefully monitoring for side effects ( 2.8 , 6 )

8.1Pregnancy Risk Summary Lithium may cause harm when administered to a pregnant woman. Early voluntary reports to international birth registries suggested an increase in cardiovascular malformations, especially for Ebstein’s anomaly, with first trimester use of lithium. Subsequent case-control and cohort studies indicate that the increased risk for cardiac malformations is likely to be small; however, the data are insufficient to establish a drug-associated risk.

There are concerns for maternal and/or neonatal lithium toxicity during late pregnancy and the postpartum period [see Clinical Considerations]. Published animal developmental and toxicity studies in mice and rats report an increased incidence of fetal mortality, decreased fetal weight, increased fetal skeletal abnormalities, and cleft palate (mouse fetuses only) with oral doses of lithium that produced serum concentrations similar to the human therapeutic range. Other published animal studies report adverse effects on embryonic implantation in rats after lithium administration.

Advise pregnant women of the potential risk to a fetus. The background risk of major birth defects and miscarriage for the indicated population(s) is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.

Clinical Considerations Dose adjustments during pregnancy and the postpartum period If the decision is made to continue lithium treatment during pregnancy, serum lithium concentrations should be monitored and the dosage adjusted during pregnancy. Two to three days prior to delivery, lithium dosage should be decreased or discontinued to reduce the risk of maternal and/or neonatal toxicity. Lithium may be restarted in the post-partum period at preconception doses in medically stable patients as long as serum lithium levels are closely monitored [see Dosage and Administration ( 2.7 ), Warnings and Precautions ( 5.1 )].

Fetal/Neonatal adverse reactions Lithium toxicity may occur in neonates who were exposed to lithium in late pregnancy. A floppy baby syndrome including neurological, cardiac, and hepatic abnormalities that are similar to those seen with lithium toxicity in adults have been observed. Symptoms include hypotonia, respiratory distress syndrome, cyanosis, lethargy, feeding difficulties, depressed neonatal reflexes, neonatal depression, apnea, and bradycardia.

Monitor neonates and provide supportive care until lithium is excreted and toxic signs disappear, which may take up to 14 days. Consider fetal echocardiography between 16 and 20 weeks gestation in a woman with first trimester lithium exposure because of the potential increased risk of cardiac malformations.

8.2Lactation Risk Summary Limited published data reports the presence of lithium carbonate in human milk with breast milk levels measured at 0.12 to 0.7 mEq or 40 to 45% of maternal plasma levels. Infants exposed to lithium during breastfeeding may have plasma levels that are 30 to 40% of maternal plasma levels. Signs and symptoms of lithium toxicity such as hypertonia, hypothermia, cyanosis, and ECG changes have been reported in some breastfed neonates and infants.

Increased prolactin levels have been measured in lactating women, but the effects on milk production are not known. Breastfeeding is not recommended with maternal lithium use; however, if a woman chooses to breastfeed, the infant should be closely monitored for signs of lithium toxicity. Discontinue breastfeeding if a breastfed infant develops lithium toxicity.

Clinical Considerations Consider regular monitoring of lithium levels and thyroid function in a breastfed infant.

🧒 Pediatric Use 44 words

8.4Pediatric Use Dosage recommendations for lithium in patients 12 years and older are similar to that of adults [see Dosage and Administration ( 2.5 )]. Safety and effectiveness of lithium in pediatric patients below the age of 12 years have not been established.

🧓 Geriatric Use 139 words

8.5Geriatric Use Clinical studies of lithium carbonate tablets did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in response between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other treatment.

Lithium is known to be substantially excreted by the kidneys, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function.

🆘 Overdosage ~1 min read

10 OVERDOSAGE The toxic concentrations for lithium (≥ 1.5 mEq/L) are close to the therapeutic concentrations [see Warnings and Precautions ( 5.1 )]. At lithium concentrations greater than 3 mEq/L, patients may progress to seizures, coma, and irreversible brain damage. Treatment For current information on the management of poisoning or overdosage, contact the National Poison Control Center at 1800-222-1222 or www.poison.org .

No specific antidote for lithium poisoning is known. Early symptoms of lithium toxicity can usually be treated by reduction or cessation of dosage of the drug and resumption of the treatment at a lower dose after 24 to 48 hours. In severe cases of lithium poisoning, the first and foremost goal of treatment consists of elimination of this ion from the patient.

Administration of gastric lavage should be performed, but use of activated charcoal is not recommended as it does not significantly absorb lithium ions. Hemodialysis is the treatment of choice as it is an effective and rapid means of removing lithium in patients with severe toxicity. As an alternative option, urea, mannitol and aminophylline can induce a significant increase in lithium excretion.

Appropriate supportive care for the patient should be undertaken. In particular, patients with impaired consciousness should have their oral airway protected and it is critical to correct any volume depletion or electrolyte imbalance. Specifically, patients should be monitored to prevent hypernatremia while receiving normal saline and careful regulation of kidney function is of utmost importance.

Serum lithium concentrations should be closely monitored as there may be a rebound in serum lithium concentrations as a result of delayed diffusion from the body tissues. Likewise, during the late recovery phase, lithium should be re-administered with caution taking into account the possible release of significant lithium stores in body tissues.

🧬 Clinical Pharmacology 142 words

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action The mechanism of action of lithium as a mood stabilizing agent is unknown.

12.3Pharmacokinetics After oral administration, lithium is reported to be completely absorbed in the upper gastrointestinal tract. Peak serum concentrations (T max ) occur 0.25 to 3 hours after oral administration of immediate release preparations and 2 to 6 hours after sustained-release preparations. The distribution space of lithium approximates that of total body water, and the plasma protein binding is negligible.

After equilibrium, the apparent volume of distribution is 0.7 to 1 L/kg. Lithium is not metabolized. Lithium is primarily excreted in urine, proportionally to its serum concentration.

Lithium is filtered by the glomerulus, and 80% is reabsorbed by passive diffusion in the proximal tubule. The elimination half-life of lithium is approximately 18 to 36 hours. Lithium excretion in feces is insignificant.
